George Drumgoole Coleman (1795 – 27 March 1844), also known as George Drumgold Coleman, was an Irish civil architect who played an instrumental role in the design and construction of much of the civil infrastructure in early Singapore, after it was founded by Sir Stamford Raffles in 1819. Only a few of his buildings have survived in Singapore, most notably Armenian Church of Saint Gregory the Illuminator, Maxwell's House (later expanded into the Old Parliament House), and Caldwell House.
